Question

我有一个REST端点。当我通过DRF GUI访问此端点时，可以手动输入数据，它可以成功运行。我的模型如下：

class Post(models.Model):
    title       = models.CharField(max_length=100, null=False)
    content     = HTMLField()
    created_at  = models.DateField(auto_now_add=True)
    authors     = models.ManyToManyField(User)

我的序列化器和视图如下：

class CreatePostSerializer(CreateAPIView):
    serializer_class = PostSerializer

class PostSerializer(serializers.ModelSerializer):

    class Meta:
        model = Post
        fields = ('title', 'content', 'authors')

当我实际上尝试通过Ajax将数据提交到端点时，就像这样：

$.ajax({
    type: 'POST',
    url: '/api/save-post/',
    data: {
    "csrfmiddlewaretoken": getCookie('csrftoken'),
    "title": "dasf",
    "desct": "dasf",
    "content": "fdasf",
    "authors": [1,2]
    },
    success: function (msg) {
        console.log(msg);
    }
});

我收到一条错误消息：{"authors":["This list may not be empty."]}，并发送了有效载荷：

title: dasf
desct: dasf
content: fdasf
authors[]: 1

我尝试将contentType更改为application / json，我尝试了几乎所有方法，但似乎没有任何效果。我该如何做才能使我的端点理解我要发送的内容？

Answer 1

var authors = [];
authors[0] = 1;
authors[1] = 2;

var arr = {
    "csrfmiddlewaretoken": getCookie('csrftoken'),
    "title": "dasf",
    "desct": "dasf",
    "content": "fdasf",
    "authors": authors
    };

$.ajax({
    url: '/api/save-post/',
    type: 'POST',
    data: arr,
    contentType: 'application/json; charset=utf-8',
    dataType: 'json',
    success: function(msg) {
        alert(msg);
    }
});

无法将数组传递到Django REST
